“…Thus, the circular electronics connects the recycling and degradable approaches. [ 31 ] Accordingly, in the near to midterm, the transient electronics could be explored to complement the current recycle and reuse approach. [1g] Nevertheless, by exploring biodegradable metals such as Mg, Fe etc., and biodegradable adhesive layer such as MICA MC‐634 and spin‐on glass, direct transfer printing has the potential for the fabrication of high‐performance transient ICs and thus, eventually replace the present recycle and reuse approach.…”

However, due to the poor charge carrier mobility, these electronic circuits do not match the performance of conventional integrated circuits (ICs) and as a result, their application is restricted to the low-end. High performance is much needed to drive advances in nearly all conventional and emerging application areas of electronics including connected systems, Industry 4.0, digital healthcare, digital agriculture, interactive systems, etc., where high-speed electronics is required to reduce the data latency. [3] In this regard, nanostructures such as nanowires, [4] nanoribbons (NRs), [5] etc. and thin films of high-mobility inorganic materials offer a viable alternative. Their performance is on par with conventional silicon-based devices, and they can also be dissolved or disintegrated in controlled environments (Table 1). [1e,1f,6]

“…This will also be an attractive direction for future electronics, as resource-efficient manufacturing could help to reduce the electronic waste and contribute to sustainability. Further, it is easier to process biodegradable materials using printing technology so that the printing technology also holds promise for future transient electronics (182)(183)(184). Several printing techniques are available today include inkjet printing (138,(185)(186)(187), transfer printing (180,(188)(189)(190)(191), contact printing (192)(193)(194)(195), and screen printing (196)(197)(198)(199)(200).…”

Touch is a complex sensing modality owing to large number of receptors (mechano, thermal, pain) nonuniformly embedded in the soft skin all over the body. These receptors can gather and encode the large tactile data, allowing us to feel and perceive the real world. This efficient somatosensation far outperforms the touch-sensing capability of most of the state-of-the-art robots today and suggests the need for neural-like hardware for electronic skin (e-skin). This could be attained through either innovative schemes for developing distributed electronics or repurposing the neuromorphic circuits developed for other sensory modalities such as vision and audio. This Review highlights the hardware implementations of various computational building blocks for e-skin and the ways they can be integrated to potentially realize human skin–like or peripheral nervous system–like functionalities. The neural-like sensing and data processing are discussed along with various algorithms and hardware architectures. The integration of ultrathin neuromorphic chips for local computation and the printed electronics on soft substrate used for the development of e-skin over large areas are expected to advance robotic interaction as well as open new avenues for research in medical instrumentation, wearables, electronics, and neuroprosthetics.

Hybrid or heterogeneous integration of silicon technologies and printed electronics is a promising approach for high-performance flexible electronics. It is essentially the integration of rigid microchips with the printed circuit on a flexible substrate. However, microchips with no-lead and millimeter-size pitch introduce practical challenges in terms of precise electrical bonding onto the printed pattern. The differences in mechanical and thermal requirements also make it challenging to use conventional bonding and interconnect technology to robustly connect the microchips on flexible substrates. The focus of this work is to present these challenges with respect to different substrateadhesive combinations and to provide a facile technique for integrating near-field communication (NFC) microchips on different flexible substrates. Following the successful integration, the smart tags were characterized to demonstrate reliable performance in the NFC reading range. While presenting a hybrid integration for the smart tag, this work also shows a potential solution for several other applications of flexible electronics where high performance cannot be achieved by printed electronics alone.
